Thanks for reporting that bug. Even when you don't change the page encoding, it doesn't support unicode.

If you want the code to the rules, it's at this link:
http://meltingwax.net/stuph/rules.tar.gz

To install:

1. Untar that so you have a folder called $KAREHA_ROOT/rules/.
2. Then, in $KAREHA_ROOT/include/rules.html, put this where you want the rules to appear:

<div id="rules-to-be-loaded" />

<script type="text/javascript">
    $.getJSON('/rules/store.json', function(data) {
      $('#rules-to-be-loaded').html(data.message);
    });
</script>
